PV for cooking
Traditional solar cookers concentrate sunlight on mirrored surfaces and convert it into heat. But this summer, Sunspot unveiled Sunspot Solar Electric Cooking, a new cooker based on PV technology. The system relies on two PV modules, a lead-carbon battery, an inverter, and an induction cooktop.

Global warming will hit solar panel performance
MIT researchers say climate change could reduce the yield of solar modules. Analysis based on the warming scenarios outlined by the IPCC predicts in some areas the annual energy output of PV systems may fall by up to 50 kWh per kilowatt installed.

Exciting excitons
A research team from Columbia University has designed organic molecules that can produce excitons with a longer lifecycle than inorganic equivalents. The excitons have the potential to amplify the amount of electricity generated by the photons a solar cell absorbs.

Nanowire mesh offers better cell performance and lower costs
A new method of creating an ordered mesh of nanowires, developed by scientists at the Lawrence Livermore National Laboratory in the United States, could lead to the creation of more efficient transparent electrode layers in solar cells – and the elimination of a rare material from the manufacturing process.

A new spectroscopic method to understand the physical principles of organic PV
A German research team claims to have created a new visualization technique it says can enable detailed mapping of the energetic landscapes of organic PV cells on a nano scale. The technique could lead to organic cells with reduced power losses.

Sandia Labs increases efforts at abusing lithium-ion batteries for safety research
According to a press release from Sandia National Laboratories, the testing lab now uses an indoor tower to drop 200-lb+ weights on lithium-ion batteries in efforts to learn more about how batteries respond to stress. This will be especially helpful in understanding how electric vehicle batteries may respond in an automobile accident.

Aquavoltaics in the Philippines
An EU funded solar-plus-storage project has been tendered in the Philippines. The United Nations is seeking bids for the system, to support the for the seaweed industry on the island of Tawi-Tawi. Combining PV with aquaculture brings many advantages for both, including water conservation, a more controlled aquatic environment, and ecosystem restoration.

Stitching together the grid of the future
A vision of a decentralized, renewable-powered electricity grid is being brought a step closer by scientists at the U.S. National Renewable Energy Laboratory. Their project, Autonomous Energy Grids, aims to take an overarching look at the solutions that will power this grid of the future, and to fill any gaps that appear between them.

The bearable lightness of solar
The weight of a thin-film rooftop PV installation at Netherlands football club AZ Alkmaar has been highlighted in media reports as a possible cause of a stadium roof collapse. However, a full investigation is yet to be launched and one German specialist said studies have shown flush-mount PV panels do not increase static wind loads on rooftops.
